So it's these little differences that you'll very quickly acclimate to but it's these stupid little syntactic details that trips off, especially those less comfortable early on because if you leave out a single character, namely that semicolon on the right hand side, nothing will work.

你会很快适应这些,微小的区别,但我们正是要把这些罗里吧嗦的语法细节,尤其是那些让人非常头大的句子啃下来才行,因为如果我们一旦遗漏掉某个符号，譬如一个分号,从另一方面看来，很有可能什么都工作不了。
